This review provides an overview of definitions and measurements of ‘Social Distance’ and attitudes children without disabilities carry towards children with disabilities. Measures include explicit and implicit approaches but clearly, the ‘Bogardus Social Distance Scale’ (A Social Distance Scale, 1933, 14 May 2014) is the most used scale in research, yet it is outdated. For a deeper look into what impacts children's ‘Social Distance’ in inclusive school settings and in order to find measurable constructs, relevant attitude questionnaires are discussed. To bring long‐used measures and attitudes together, a comprehensive model of ‘Social distance’ is introduced. This model integrates the classical view on ‘Social Distance’ as interaction willingness with feelings associated with this interaction and includes attitudes children carry towards individuals and towards the group the interaction partner is believed to belong to. In summary, this paper shows the need for a more comprehensive and precise measure on how school children really engage with one another.  相似文献   

The influence of gate start position on physical performance and anxiety perception in expert BMX athletes

The critical importance of the start phase in bicycle motocross (BMX) racing is increasingly acknowledged. Past experiments underlined that the internal lane of the starting gate provides a strong positional advantage. However, how lane position affects start performance and cognitive and somatic state anxiety remains unexplored. We examined the start performance and anxiety responses of youth national-level BMX riders in both experimental and ecological contexts. We used contextualization motor imagery routines to evaluate start performance and state anxiety from the internal and external lanes. Cycle ergometer measures revealed a better start performance from the external lane, but we did not record any lane effect on actual gate start times. Both somatic and cognitive anxiety scores were higher before racing from the internal compared to the external lane. Finally, state anxiety (i.e., somatic anxiety, worry and concentration disruptions) negatively predicted the start performance. Present findings provide original insights on psychological factors involved in BMX start performance, and might contribute to fruitful coping interventions and training programmes in sports overlapping the framework of “handicap races” taking the specific form of positional advantages/disadvantages at the start (e.g., ski/snowboard cross, athletics, swimming, motorsports, etc.).  相似文献   

A biomechanical comparison of countermovement performance after short-term traditional and daily-undulated loaded vertical jump training

In order to assess lower extremity muscle mechanical properties in athletes, power-load characteristics during multi-joint tasks are frequently examined. This work compared 6 weeks of traditional (TP) and daily-undulated (DUP) periodized loaded countermovement jumping (CMJ). 20 amateur athletes (age: 24.2 ± 2.6 years, height: 175.6 ± 7.1 cm, body mass: 71.5 ± 7.7 kg, 10 males/10 females) exercised three times weekly using maximal CMJs with loads corresponding to 0%, 15% and 30% of body mass. Prior to the training period, subjects were once-only assigned by random to either the TP or DUP training scheme. Pre-to-post training, maximal center of mass (COM) -height, -take-off velocity, -power output and -impulse were compared during CMJ with additional loads corresponding to 0–30% of body mass. ANOVA (time * group) with repeated measures revealed significant (P < 0.05) temporal gains of maximal COM-height (2–11%), -take-off velocity (1–7%), -power (2–8%) and -impulse (3–9%) over most loading conditions for TP and DUP. However, ANOVA indicated no group effects for any outcome. Independent from the periodization model, maximal power output remained statistically unchanged with increased testing loads. For short-term conditioning periods, TP and DUP were equally effective in enhancing biomechanical jumping variables under varying loading conditions.  相似文献   

The Swedish riding school: a social arena for young riders     

Gabriella Thorell  Christian Augustsson  Owe Stråhlman  Karin Morgan 《Sport in Society》2018,21(9):1416-1431

The aim was to explore how young riders experience the riding school. By analysing focus groups interviews, a picture emerged showing that young riders’ main motive for participating at riding schools was the social aspects. Riding schools could be characterized through an institutional perspective in which the young riders became internalized and socialized into a stable culture. The young riders identified with the norms and values of the riding instructors through master–apprentice learning. In addition, the results revealed a change in the stable culture since the instructors encouraged social interactions and participation in the community that became central to learning and development. Opportunities to influence and interact were important for the individuals and from a child’s rights perspective. Through participation in the community of practice at riding schools, young riders not only learn about riding and horse management but also develop important personal social skills.  相似文献

Tracing the links between science and technology: An exploratory analysis of scientists’ and inventors’ networks   总被引：1，自引：0，他引：1  

Stefano Breschi  Christian Catalini 《Research Policy》2010,39(1):14-26

The paper provides an exploratory analysis of the research networks linking scientists working in an open science environment, and researchers involved in the private technology domain. The study combines data on scientific co-authorship with data on patent co-invention, at the level of individual researchers, for three science-intensive technology fields, i.e. lasers, semiconductors and biotechnology, in order to assess the extent of the overlap between the two communities and to identify the role of key individuals in the process of knowledge transfer. Our findings reveal that the extent of the connectedness among scientists and inventors is rather large, and that particular individuals, i.e. authors-inventors, who act as gatekeepers and bridge the boundaries between the two domains, are fundamental to ensuring this connectivity. These individuals tend to occupy prominent positions in the scientific and the technological networks. However, our results also show maintaining a very central position in the scientific network may come at the expense of being able to fill a similarly central position in a technological network (and vice versa). Finally, preliminary analysis of the institutional origins of authors-inventors shows that one characteristic, distinctive of Europe compared to the United States, is associated with the relatively lower involvement of corporate scientists at the intersection between the two worlds of science and technology.  相似文献   

Implementation Factors and Their Influence on Student Mathematics Outcomes     

Tasia Brafford  Beth Harn  Ben Clarke  Christian T. Doabler  Derek Kosty  Kathleen Scalise 《Learning disabilities research & practice》2023,38(1):5-14

Assessing implementation allows for a better understanding of an intervention's effects and the mechanisms that influence its impact. Two main areas of implementation are (a) the quality with which an intervention is delivered and (b) instructors’ adherence to the programmed intervention. The current study used data from a kindergarten mathematics intervention program to (a) examine if and how treatment adherence was associated with implementation quality and (b) explore implementation measures’ relation to student mathematics outcomes. Results indicated high implementation scores across time for both adherence and quality. Neither treatment adherence nor implementation quality was found to relate to a general outcome measure of student mathematics achievement; however, both were similarly related to the curricular-aligned measure.  相似文献   

Does having vulnerable friends help vulnerable youth? The co-evolution of friendships,victimization, and depressive symptoms in Chinese adolescents' social networks

This study examined whether having vulnerable friends helps or hurts victimized and depressed (i.e., vulnerable) adolescents and whether this depends on classroom supportive norms. Students (n = 1461, 46.7% girls, 93.4% Han nationality) were surveyed four times from seventh and eighth grade (M_age = 13 years) in 2015 and 2016 in Central China. Longitudinal social network analyses indicated that having vulnerable friends can both hurt and help vulnerable adolescents. Depressed adolescents with depressed friends increased in victimization over time. Victimized adolescents with victimized friends increased in victimization but decreased in depressive symptoms. These processes were most likely in classrooms with high supportive norms. Having friends and a supportive classroom may hurt vulnerable adolescents' social position but help victims' emotional development.  相似文献
